Specification of Letters Patent.

Patented July 14-, 1914.

Application filed April 16, 1913. Serial No. 761,544.

To all whom it may concern: Be it known that I, GUs'rAvE'F. MORANZ,

a citizenof the United States, anda resident of the city of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Dry-Kilns, of

which I do declare the followin to be a full,

clear, and exact description, re erence beingv is especially well suited for the drying of articles such as piano cases, carriages, or the like, that have been painted and varnished and which require tobe very carefully and uniformly dried.

The invention consists in features of novelty'hereinafter described, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of this specification.

Figure 1 is a View in vertical section through a dry kiln embodying my invention, this view being taken on line 1-1 of Fig. 3. Fig. 2 is a plan view of dry kiln embodying my invention, parts being shown in horizontal section. Fig. 3 is a view in vertical section in line33 of Fig. 1. Fig. 4C is a view in vertical section on line H of Fig. 1.

' My improved dry kiln is shown as comprising a drying room or chamber 10, having double walls 11 and 12, the inner wall 12 being preferably faced or covered with "sheets of metal 18. One of the vertical walls of my improved kiln will be furnished with apart by strips 17, as shown. Between the studding 16 of the vertical walls, adjacent the bottoms of the walls, extend the strips or plates 18, these plates being spaced a slight distance above the floor of the kiln (preferably about two inches) so as to form inlet openings 20 that extend substantially from end to endof the kiln (see Figs. 1 and 4:).- j

The floor of myimproved kiln is shown as arrangedin line with the floor 22 of the adjoining room of the building wherein the kiln is located, or upon a level with the surface from which the material will be introduced in to the kiln. My improved floor is formed of removable'sections, three of such sections being shown in the accompanying drawing. Each of these floor sec tions consists of two layers, preferably of wood, the upper and under layers being formed of strips of different widths and so spaced apart that the'continuity of the air currents through the double floor will be broken. Preferably the under layer of the floor consists of wooden strips 25, say three inches in width, and spaced say two inches apart, to form openings between the strips, while the upper layer of flooring consists of narrower strips 27 (say 2% inches wide) set more closely together to form the narrow spaces 28 between such strips. The spaces 26 between the strips 25 of the under layer of the flooring are arranged beneath the strips 27 of the upper layer of the flooring,

so that as the heated air passes upward through the flooring, continuity of the air currents willv be broken and a very uniform distribution of the air throughout the entire body of the kiln will be effected. The upper and lower layers of the flooring will be spaced apart by longitudinal strips 29 to which the upper and lower strips 27 and 25 will be fastened.

Beneath the flooring of the kiln extend the joists or stringers 30, whereon the flooring is removably supported. These joists or stringers 30 are set at convenient distances apart and at their ends extendthe transverse joists 31.

Beneath the inner walls. 12 of the ends of the kiln extend the strips 34 from which depend the baffle-plates 35 that extend between the joists 30, and these baffie-plates form, with the joists 31, the air conduit'36, whereby air will pass from the air-inlet openings 20.

Between the joists or stringers :30 are arranged the heating pipes 40 that will be connected to suitable supply pipes or headers, in a manner well understood by those familiar with this class of structures.

- Theair-outlets charge of the heated' 'air from the difl'erent I parts of the kiln.

Both the air-inlets 20 and the air-outlets 45 are provided with improved construction of valves whereby the passage of air there-: through can be most conveniently and accurately regulated. The valve'for'each of'the links 51, theupper ends of which are pivotally attached, asat 52, to the side wall of the kiln; These hanger-links 51 give to the valve-plate 50 a parallel ruler movement and while allowing the valve-plate to bereadily shifted to open or'close the air-inlet 20, in-

sures an accurate-opening and closing of the air-inlet throughout its entire length.

In order to hold the valve-plate 50 at any "desired position, one of the links 51 (see ltig. 4;) is-provided with a series of notches 53 adapted to be'enga ged by a dog or pawl 54 that is pivo-ted, as at 55 upon a standard 56. It will be readily understood that by shiftihg the position of the dog or pawl 54, the valve-plate '50 may beheld at any desired elevation. Y a

' I 45, in the roof of the kiln are provided each with a valve-plate 50?, similar in construction to the valve-plate 5,0 jnstdescribed. Each of these valve plates hp isipivotally, connected to'links51 the outer ends of whichare pivoted," as at 52, to the 'rooif. iBy preference, the end' of each the valve-plates'5O is provided with a loentn'or upturned portion 58, to permit the valve-plate 50? to be conveniently shifted, b t na c s e c va vep 'te 5 r sts upon the roof, it is not necessaryto provide any" device for holding the "valveplate 50? inadjusted position. From the foregoing description, it will be seen that when the valve-plates "50 and 50? have been adjusted so asto openthe-inlets x20 qiitlets 45 of the kiln to the required .ergtent; air will pass through the inlets 2Q and down the passageways 36 below the baf fle-plates 35 and into the spaces between the joists or stringers 30 andbeneath the floor; He e the ai will be heated by the steam pipes i0; and thus heated, will rise through: the spaces 26, and 28 formed in the floor of the kiln. Thespaces 26 and 28 betweenthe slats comprising the upper and lower layers of the floor being out of alinement, a most thorough and uniform-admission of the heated air into the body ofthe kiln will be I have remain practice that a most uniform heating of the'body ofair within the kilncan bejsecured. l'lhis feature par-f I stri s of he l er ays-r? seciired. By means of the plurality of long,
